9. Equipment Operation
Operation of the Nest Case shall be carried out by trained personnel that are familiar with
the STRYDE system.
The Nest Case shall be operated indoors within the temperature range described in the
technical specification. The Nest Case is a part of the STRYDE Nimble System and can be
scaled to suit the customer’s needs by adding additional Nest Cases. The Nest Case will
typically be located at the local operations hub for the duration of a seismic survey.
The Nest Case shall be powered by a single-phase mains supply as described in the technical
specification section.
The primary purpose of the Nest Case is to harvest data from and recharge the lithium ion
batteries in the Nodes (and/or recharge the lithium ion batteries in the Initialisation Device)
that are used for the seismic survey. The Nest Case shall only be used to recharge and harvest
data from: Nodes that have been inspected for damage; and are clean and dry. Damaged
Nodes shall not be used with the Nest Case and instead they should be decommissioned when
returned to the local operations hub.
The Nest Case can recharge and harvest data from up to 90 Nodes simultaneously, accepting
a tray of 90 Nodes (or up to 70 Nodes with 4 Initialisation Devices that are placed on a
bespoke jig). The Nodes are placed into the magazine with the optical port facing upwards
and the magazine are placed on to a Shelf and raised into the charging position by pushing
down the level of the scissor lift. The STRYDE System Case connected to the Nimble System can
then be used to monitor the state of charge and view diagnostics for each optical link.
Recharging of the Nodes is done using the wireless QI standard, with each Node having its
own battery management circuit that is used to regulate the rate of charge and terminating
charging once the battery reaches a pre-determined level. The data harvesting is performed
using a bespoke bi-directional optical link, the data from the Node is then packetized by the
Nest board and sent over ethernet. The charging and harvesting time will take no more than 4
hours.
There are 90 Nest boards (corresponding to 90 Nodes), each with its own 100Mb ethernet
link, these are routed to a switch where they are combined and then output over 1Gb
ethernet.
Charging shall be done away from flammable materials, and a fire extinguisher shall be
within reach for emergency use.
The outer case of the Nest Case shall only be cleaned when the outer water-tight lid is fitted.
The outer case shall only be cleaned by hand with warm soapy water.
All other parts of the Nest Case shall only be cleaned with a dry soft cloth. Don’t use alcohol
or other cleaning solutions.
